Abstract

The invention discloses phase-change energy-storage temperature-regulating foam concrete and a preparation method thereof. The phase-change energy-storage temperature-regulating foam concrete is prepared from 100-500 parts of phase-change energy-storage particles, 800-1000 parts of ordinary portland cement, 0-100 parts of quick-hardening cement, 0-300 parts of a filler, 5-10 parts of an accelerator, 5-10 parts of fibers, 0.5-1 part of a thickening time control agent, 2-6 parts of a foam stabilizer, 20-60 parts of a waterproof agent, 400-700 parts of water and 30-100 parts of a foaming agent. The preparation method comprises the steps of S1, preparing the phase-change energy-storage particles; S2, mixing the ordinary portland cement, the quick-hardening cement, the filler, the phase-changeenergy-storage particles, the accelerator, the fibers, the thickening time control agent, the foam stabilizer and the waterproof agent, adding water, mixing and stirring for 2-4 minutes, adding the foaming agent, stirring for 5-15 seconds, pouring into a mold, and standing and foaming for 1-24 hours; S3, after foaming is finished, conducting demolding and curing, and obtaining the phase-change energy-storage temperature-regulating foam concrete.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a phase-change energy storage temperature-adjusting foam concrete and a preparation method thereof. Background technique [0002] Energy saving and emission reduction is the basic national policy of our country, and building energy saving is the top priority. At present, my country's existing buildings are about 43 billion square meters, more than 95% of which are high-energy-consuming buildings; the area of ​​new urban and rural buildings is nearly 2 billion square meters each year, of which more than 80% are high-energy-consuming buildings. The thermal insulation performance of buildings in my country is generally poor, and the heating energy consumption per unit area is about 2 to 4 times that of developed countries. my country's building heating is generally dominated by coal-fired buildings. According to statistics, 190 million tons of carbon dioxide are emitted every year by heating...
